Fix f_version type: should be u64 instead of unsigned long
Fix f_version type: should be u64 instead of long There is a type inconsistency between struct inode i_version and struct file f_version. fs.h: struct inode u64 i_version; and struct file unsigned long f_version; Users do: fs/ext3/dir.c: if (filp->f_version != inode->i_version) { So why isn't f_version a u64 ? It becomes a problem if versions gets higher than 2^32 and we are on an architecture where longs are 32 bits. This patch changes the f_version type to u64, and updates the users accordingly. It applies to 2.6.23-rc2-mm2.
